DEVICE FOR LIGHTING LAMPS BY ELECTRICITY,

SPECIFICATION forming part of Letters Patent No. 638,565, datedSeptember 26, 1899.

Application filed February 5| 1898. Serial No. 669,237. (No model.)

To all whom it may concern;

Be it known that we, HENRY H. BRIGHAM and SvEND MARTIN MEYER, citizensof the United States, and residents of the city of New York, State ofNew York, have invented a new and useful Improvement in Devices forLighting Lamps by Electricity, of which the following is aspecification.

The subject of our invention is a device comprising aslidingbar mountedon the lampburner and carryinga resistance-coilof platinum wire or thelike adapted to be rendered incandescent by a current of electricity,the movement of the barserving to throw the coil into contact with orproximity to the wicker tip of the burner and also to close an electriccircuit, so that when in lighting position the coil will be renderedincandescent and when in retracted position the circuit will be brokenand the coil will be removed from the flame of the lamp.

In the accompanying drawings, Figure 1 is a vertical section of alamp-burner, illustrating one form of our invention. Figs. 2, 3, and Iare detail views of the movable coil carrying device on a larger scale.Fig. 5 is an elevation, partly in section, of the lamp reservoir andburner, illustrating a mode of making electrical connection between theshell of the burner and the lamp-reservoir, in the base of whichasuitable batteryor source of electricity is located. Fig. 6 is apartial section of the lamp-burner,illustratinga modification.

1 represents the lamp reservoir, 2 the burner, and 3 the cone of theburner, which surrounds the lamp-wick.

6 represents a tubular rod mounted in nearly vertical position withinthe lamp-,

burner 52, having a longitudinal sliding movement in a socket 4 anddrawn down by a spring 13. (Shown in Figs. 8 and 4.) A metallic rod 7,rigidly connected to the interior of the sliding tube 6 and inelectrical contact therewith, is connected at its upper end to aplatinum coil 8, the other extremity of which is connected to aninsulated metallic rod 9, connected by an insulated wire 9 with anexternal cap 10, which is mechanically connected to the bottom of thetube 6, but electrically insulated therefrom by suitable insulatingmaterial 11. The contact of the sliding tube 6 with the fixedguiding-socket 4, in which it slides, places the said tube in constantelectrical connection with the lampburner 2, and consequently with theshell of the reservoir or body 1 The act of sliding up the tube 6 movesthe coil 8 into contact with or close proximity to the wick or tip ofthe burner and at the same time throws the metallic cap 10 intocontactand electrical connection with a contact-point 14 on theextremity of a conductor 14, which terminates in a socket 15, mounted inan insulator 15 in convenient position for connection or disconnectionwith an insulated conductor 19, connected to one pole of a battery 20,the other pole of which is grounded by a conduc' tor 21 in the lamp-body1.

In Fig. 5 we have shown a suitable mode of making the connection in alamp without re movable fount. This consists ina rod 16, slidingvertically in the terminal socket 15 and slipping at its lower end in ametallic socket 18", mounted on the upper end of an insulated wire 18,which passes down through a fixed tube 1 in the body of the lamp and isconnected at its lower end by a wire 19with one pole of a battery 'orsuitablesource of electricity 20, located in the base of the lamp, theother pole of which'is grounded at 22 on the lamp-body 1 by aconducting-wire 21. The socket 18 is held in position and insulated byan annular cap 17, of insulating material, mounted in top of thelamp-body 1.

It will be apparent from this description that by slipping up the wirerod 16 within its conncctingsocket 15, thereby raising it completelyclear of the conducting-socket 18 and the insulating-socket 17, theburner 2, with its electric attachments, is freed from the lamp-body, sothat it may be removed therefrom, as in the case of an ordinary lamp.

The retraction of the bar 6 is effected by spring or gravity the momentit is released. This removes the coil from the flame, con-' ceals itwithin the guiding-socket 4t, and at the same time breaks the electriccircuit, thus preventing any injury to the coil or exhaustion of thebattery in the normal condition of the apparatus and excepting at theinstant of lighting the lamp.

In the modification shown in Fig. 6 the circuit is closed by anupward-sliding movement of the chimney-gallery 5 and the neck 5, towhich it is attached within the shell 2 and cone 3 of the burner. Inthis illustration the tube 6 is permanently connected to the neck 3 ofthe cone or chimney-gallery and contains rods '7 and 9, as in Fig. 2, onwhich the lighting-coil 8 is mounted, the one rod being in electricalconnection with the tube 6, while the other, 9, is insulated therefromby insulating-sleeve 9" and terminates below in a contact-head 10, whichby the upward movement of the chimney-gallery and attached parts makescontact with the arm lat, connected to the insulated conducting-socket15, as shown in dotted lines, thereby closing the circuit through thecoil 8 at the same time that this is elevated in contact with or,proximity to the wick. The rod 7, (shown in Fig. 2,) by which thegrounded connection is made between one end of the coil 8 and the tube6, is hidden in Fig. 6. In this illustration the electric connection ofthe tube 6 with the metal body of the lamp may be by its directattachment of the said tube to the neck 5 of the chimney-gallery and thesliding contact of this with the burner-shell 2, or this groundconnection may be made by the contact of the upper end of the tube 6with fixed cone 3 of the burner, as shown in dotted lines.

Having thus described our invention, the following is What we claim asnew therein and desire to secure by Letters Patent:

1. An electrical device for lighting lamps comprising a suitable sourceof electricity and conductors; a resistance-coil adapted to be renderedincandescent by the electric current; a sliding bar mounted on theburner, and on which the coil is mounted, and whereby it is carried toand away from the wick or igniting-point of the burner, and a contactdevice with which the coil-carrying bar engages so as to close anelectric circuit through the coil in the act' of moving the coil intolighting position as explained.

2. An electrical device for lighting lamps, comprising a resistance-coiladapted to be rendered incandescent by an electric current, a slidingbar on which said coil is mounted and the movement of which advances thecoil to position for lighting the burner and retracts it from suchposition, a suitable source of electricity and conductors, connected atone end with the movable bar and terminating at the other end in acontact-point with 1 which the movable bar forms electric connection soas to close a circuit through the coil in the act of moving the coilinto igniting position, substantially as explained.

An electrical device for lighting lamps, comprising a suitable source ofelectricity, conductors connected therewith, a sliding bar mounted onthe lam p-burner connected with one pole of the conductors and adaptedby its movement to make and break connection with the other pole andhaving an insulating device interposed between its ends which thusconnect with the respective poles of the battery, and a resistance-coilcarried by the sliding bar and electrically connecting the ends thereof,whereby the forward movement of the bar will close an electric circuitthrough the resistance-coil and advance the said coil to lightingposition and the retraction of the bar will break such circuit andremove the lighting-coil from the flame of the lamp as explained.

4;. An electrical device for lighting lamps comprising a suitable sourceof electricity, and conductors, a resistance-coil adapted to be renderedincandescent by the passage of an electric current, a sliding bar inwhich said coil is mounted, adapted to be advanced by pressure of thefinger and retracted automatically when released, and in its advancemovement carrying the coil to lighting position and at the same timeplacing its ends in electrical connection with the respective poles ofthe conductors, thereby closing an electric circuit through said coil,as explained.

5. In an electrical device for lighting lamps the combination of asuitable source of electricity and conductors connected therewith, acoil adapted to be rendered incandescent by the electric current, asliding bar, carrying the said coil, mounted in the lamp-burner andadapted in its forward movement to carry the coil into lighting positionand also close an electric circuit therethrough, and a shield or casingwithin which the said coil is concealed in its retracted position,substantially as set forth.
